LANSING – As fans ready to watch the Spartans take on Duke in the Final Four on Saturday, and as the rising temperature signals the coming concert and festival season, Attorney Bill Schuette warns Michiganders to be wary of online ticket scams.

In a news release, Schuette said online ticket-buyers should buy from known vendors or thoroughly research unfamiliar vendors, use a credit card so questionable charges can be disputed with creditors later, look for "https" before web addresses to indicate a secure site, and inspect tickets afterward for any irregularities.
